Engineers discover that the electric potential between two electrodes can be modeled as V(x)=V0ln(1+x/d), where V0 is a constant, x is the distance from the first electrode in the direction of the second, and dd is the distance between the electrodes.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
